To'all'who'wt time?) concern: x g B it known that I, Wreeimrqx ADAMs, a citizen of the United States, and resident of the city: Of Chicago, countyof 0 6k, ant-11 Stated of Illinois, have invented certain nevv' and usefuldmprovelnents in Car-Wheels, of which the following is a specification; I v p H M fl invention'relat'es ,te improvemen in car Wlieels,"especia y of tliatclass used'in connection ivith raihvavnioto'r cars, has for its object the productionof wes- 1 of this character Whichfwill be of durable and economical constructionfand which will be highly ehi cient in use I A x g A further object is the production of ca'r vhfeel of the character nien'tione'd, which will bi so constructed to permit of ready; arid" expeditious substitution orrenewal. of a orn part, and hic hwill be'eflect ually reinforced at the place ordinarily subjected it i r e w a t er to:ete Wb nl: the life of the v'h'eel.

For rei forcenaent the outer edg of rirri: secinonjlO is formed w th a turnedback an;

tion, 11 is formed .With "an ou'tn aidly p ojecting, 'annulaiiflange, 20 which cons'tit' theflange proper of the heel. It has been found that in use, the inner of flange,-

20 is subjected. to atr'erne'ndous wear and it has been "found, that this flange, .Wh'ere fun;

protected and not re'ihfiarcediwearsTout m h of pthei? we 0.15 he heel, 5 sitatingdi scarding or scrafipingo'f the Wheel, iro'tivithstanding that the other parts thereof are still in good 2 condition and practiscally I unwornl [I 1n order to rein force and protect this flange, I have lp lrovi'ded n ag ula-r guard .orplate, 23 Whicl rinay be spun over said fi'an'g as seenin Fig: 2', or secured thereto. asbjf rivets,2fL, as, seen in Fig. WViththisarrangement, the n1 ember23 Will receive anjdbearall 'o'fthe ,Weari which@other- Wise would (be; directed against the flange,

20, and upon said member 'beco'niing qra or disabled, the saine inay be removed, and a new one inserted in its place. Thus the life of th -wheel, as is apparent, will be greatly extended.

e et f e silflla c j 1. n heievsnt of ear or disabhn'giof either of saidparts 15, said parts 12,.13 l l being projecting flanges, 12 and 13 of the rim being located intermediate the lateral edges of the rim, renders it possible to connect the same directly to the wheel center part or spokes, without the use of a felly, such as is employed in the conventional construction of wheels of this character.

In Fig. 5 is shown a rim construction practically the same as that described, except that in this construction the inner edges of the flanges, 12 and 13 are united, the entire rim being formed of a single piece. The advantages last pointed out with reference to avoiding the necessity of'employment of a felly obtains with equal force to this construction. In this construction also and in Fig. 6 are shown flanges 21 of another design which may be employed, the turned back portions 22 of said flange, as here shown lending, of course, additional strength and rigidity to the rim. 7

In Fig. 4 the rim 25 is of an integral construction, being provided with an inwardly projecting medial flange, 26, said rim and flange being of a drawn construction, or, if desired, the rim may be formed from a flat strip and the flange, 26 welded thereto. In this construction, also, a wheel center part, 27, is shown of metallic construction, which is secured to said flange by rivets, 28. The employment of a metallic center part, of course avoids the necessity of using a washer plate such as 17, which is employed where I the center part is of, wood.

- fore do not wish to be limited to the While I have illustrated and described the preferred forms of construction for carrying my invention into effect these are capabio of variation and modification. I thereprecise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims. 7

i What I claim as new and desire to secure by Letters Patent of the United States-is:

1. A car wheel comprisinga rim divided on a circumferential line positioned intermediate the lateral edges thereof; inwardly projecting flanges provided on the divided portions of the rim at the meeting edges thereof; and a center part connected with said flanges.

2. A car wheel comprising a rim divided on a circumferential line positioned intermediate the lateral edges thereof; inwardly projecting flanges provided on the divided portions of the rim at the meeting edges thereof, the inner edges of said flanges being united; and a center part connected with said flanges.

3. A car wheel'comprising a rim formed of two annular sections detachably connected together at their inner sides.

4. A car wheel comprising a rim formed of two annular independent sections; a wheel center part; and means arranged at the inner side of the rim for detachably connecting said rim sections and center part.

5. A car wheel comprising a rim formed of two annular sections arranged side by side with contacting edges; inwardly projecting flanges at said edges; and means for detachably connecting said flanges.

('3. A car wheel comprising a rim formed of two annular sections arranged side by side with contacting edges; inwardly projecting flanges at said edges; a wheel center part registering with and contiguous to said I part registering with and contiguous to said flanges; a washer plate arranged at the opposite side of said center part; and means for connecting said flanges, center part and washer plate.

8. A car wheel comprising a rim having an outwardly projecting annular flange; and a reinforcing element embracing said flange and covering the inner side thereof.

9. A car wheel comprising a rim'having an outwardly projecting flange; and a reinforcing element secured to said flange and extending over the inner side and outer edge thereof.

10. A car wheel comprising a rim having an inwardly projecting medial flange; and offset annular flanges formed at both of the lateral edges of said rim.

11. A car wheel, comprising a rim, formed of two annular independent sections; and means at the inner side of said rim for connecting said sections together.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
